AirPods Pro discharging when in charging case
My AirPods Pro discharge randomly in the closed case. It will be one side or the other. But one will wind up at 0% while the other is at 100%. They seem to be connecting to Bluetooth even when the case is closed. Although my AirPods are both capable of charging, and normally do just fine, perhaps 1 in every 6 charges results in one of hte AirPods actively discharging while sitting in the charging case. I have done all the available troubleshooting and cleaning. In addition, I took them to the Apple Store because they were still covered by AppleCare. The technicians ran the AirPods Pros through a test and gave me a new pair. Unfortunately, the new pair behaves exactly the same. I returned to the Apple Store and the technicians ran the charging case through a testing device, but determined that the case was fine. Any suggestions? Do I need to check Bluetooth settings after I put the AirPods into their case to make sure they are no longer connected to my iPhone when they are in the case? Thanks!
